Electrician's mate vs improver vs electrician - what's the difference?

[Electrics]

I see mates jobs asking for quals and duties to include pulling cables, termination, chasing, patching, snagging, fixing issues, basically everything except testing and inspection.

So what is a mate really and how is it different from a bonafide electrician? Is it just the qualifications? Because the jobs seem almost identical to me.

What about an 'improver'? Where does he fit in?

A 'mate' is someone who works for some cash , an improver not much 'cash' and an electrician 'loads of cash'
